ExtJS/JS : DataView automatically scrolling up in IE?

In Internet Explorer(tested with IE11), the clicking on a dataview item will cause that item to automatically scroll to the top. To re-create the issue, paste the following code into ExtJS documentation fiddle, run the fiddle, scroll all the way to bottom, and then click on one of the images. This will cause the dataview to scroll up automatically.
Ext.define('Image', {
extend: 'Ext.data.Model',
fields: [
{ name:'src', type:'string' },
{ name:'caption', type:'string' }
]
});
Ext.create('Ext.data.Store', {
id:'imagesStore',
model: 'Image',
data: [
{ src:'http://www.sencha.com/img/20110215-feat-drawing.png', caption:'Drawing & Charts' },
{ src:'http://www.sencha.com/img/20110215-feat-data.png', caption:'Advanced Data' },
{ src:'http://www.sencha.com/img/20110215-feat-html5.png', caption:'Overhauled Theme' },
{ src:'http://www.sencha.com/img/20110215-feat-perf.png', caption:'Performance Tuned' }
]
});
var imageTpl = new Ext.XTemplate(
'<div class="abc">',
'<tpl for=".">',
'<div style="margin-bottom: 10px;" class="thumb-wrap">',
'<img src="{src}" />',
'<br/><span>{caption}</span>',
'</div>',
'</tpl>',
'</div>'
);
Ext.create('Ext.view.View', {
store: Ext.data.StoreManager.lookup('imagesStore'),
tpl: imageTpl,
itemSelector: 'div.abc',
emptyText: 'No images available',
renderTo: Ext.getBody()
});
Is there any way I can stop this automatic scrolling ? This only happens in IE(the scroll position remains unaffected in FF and Chrome).

How to display the message below the comboBox dropdown

I created a comboBox,
var states = Ext.create('Ext.data.Store', {
fields: ['abbr', 'name'],
data : [
{"abbr":"AL", "name":"Alabama"},
{"abbr":"AK", "name":"Alaska"},
{"abbr":"AZ", "name":"Arizona"}
]
});
Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose State',
store: states,
queryMode: 'local',
valueField: 'abbr',
renderTo: Ext.getBody(),
// Template for the dropdown menu.
// Note the use of "x-boundlist-item" class,
// this is required to make the items selectable.
tpl: Ext.create('Ext.XTemplate',
'<tpl for=".">',
'<div class="x-boundlist-item">{abbr} - {name}</div>',
'</tpl>'
),
// template for the content inside text field
displayTpl: Ext.create('Ext.XTemplate',
'<tpl for=".">',
'{abbr} - {name}',
'</tpl>'
)
});
below the drop down I wanted to display some messages.
Can anybody give some idea which component I will use or how to display some message below the drop down. Please check in screenshot.

You can override the renderTpl of Ext.view.BoundList, like:
listConfig: {
renderTpl: [
'<div id="{id}-listWrap" data-ref="listWrap"',
' class="{baseCls}-list-ct ', Ext.dom.Element.unselectableCls, '">',
'<ul id="{id}-listEl" data-ref="listEl" class="', Ext.baseCSSPrefix, 'list-plain"',
'<tpl foreach="ariaAttributes"> {$}="{.}"</tpl>',
'>',
'</ul>',
'<div style="border: solid 3px #000; padding: 2px;">Message</div>',
'</div>',
'{%',
'var pagingToolbar=values.$comp.pagingToolbar;',
'if (pagingToolbar) {',
'Ext.DomHelper.generateMarkup(pagingToolbar.getRenderTree(), out);',
'}',
'%}', {
disableFormats: true
}
],
}

tpl inside of Items[] on Sencha Touch 2

I am trying to add this code in Sencha Touch, but it´s not working..
items: [
{
xtype: 'label',
tpl: ['<div class="label">{[c.Text.getText("SC_ORDER_A_TOTAL_NET_AMOUNT")]} </div>' +
'<div class="total-value">{netamount}</div>' +
'<div class="indicator {lightstatus}">{lightvalue}</div>'].join()
}
]
Maybe, it´s not possible to do this.. any clue? I need to configure different labels with different hidden option, sometimes it´s true and sometimes it´s false.

This is working for me:
{
xtype: 'label',
tpl: '<tpl if="doShow"><div style="color:red;">It is raining {textFromData}</div></tpl>',
data: {textFromData:'Cats and Dogs'}
}

Sencha Touch: how to get config from tpl?

With Sencha Touch, I created a component to display a table for my mobile application.
Here's my component code:
Ext.define('MyApp.components.table.Table', {
extend: 'Ext.Container',
xtype: 'table',
config: {
cls: 'myTableCSS',
scrollable: 'vertical',
tpl: Ext.create('Ext.XTemplate',
'<tpl for=".">',
'<table>',
'<tr>',
'<tpl for="headers">',
'<th>{html}</th>',
'</tpl>',
'</tr>',
'<tpl for="rows">',
'<tr class="{[this.config.id]}" >',
'<tpl for="columns">',
'<td>{html}</td>',
'</tpl>',
'</tr>',
'</tpl>',
'</table>',
'</tpl>'
}
});
Here's my view implementation:
xtype: 'table',
id: 'myRedTable',
data: [
{
headers: [
{ html: 'firstname' },
{ html: 'lastname' },
{ html: 'age' }
],
rows: [
{
columns: [
{ html: 'John' },
{ html: 'Smith' },
{ html: '38' },
]
}
]
}
],
In my component, when I use {[this.config.id]} I would like to get the id of my view implementation (i.e. myRedTable) but it doesn't work.
Is there any solution to achieve this?

It seems you wrote the syntax for inline arbitrary code correctly, but there's a problem with scope. this refers to the instance of Ext.XTemplate itself, not the table view.
You should try another way to get the reference of your table instance instead, for example, in your table's definition file:
initialize: function(){
var me = this;
me.setTpl('Ext.XTemplate',
// blah blah ...
// now you can use "me" to refer to your table instance
)
}

Sencha Touch List 'sticks' when in a Panel with other elements

I have a Panel where I would like to have some other elements in it and a list. When I have the list in the parent panel on it's own, the list functions properly. However, when I add another item to the parent panel, the list now won't scroll downward (it's no longer constrained to the size of the screen).
This is how I'd like my layout to be:
Viewport
|--------------------|
| Revenue Panel |
|--------------------|
| EventList |
| |
|--------------------|
Though the list appears to be getting rendered offscreen for all of the data in it's store.
This is what I have for my view:
DashboardIndex.js
shopifymobile.views.DashboardIndex = Ext.extend(Ext.Panel, {
dockedItems: [
{
xtype: 'toolbar',
title: 'SHOP NAME',
dock: 'top',
defaults: {
iconMask: true,
ui: 'plain'
},
items: [
{xtype: 'spacer'},
{
iconCls: 'refresh',
listeners: {
'tap' : function(){
shopifymobile.stores.onlineEventStore.load();
}
}
}
]
}
],
layout: 'fit',
fullscreen: true,
});
Revenue.js
shopifymobile.views.RevenuePanel = Ext.extend(Ext.Panel, {
styleHtmlContent: true,
flex: 1,
items: [
{
tpl: [
'<div class="revenuepanel">',
'<div id="revenuedata">',
'<h3 class="label">TODAY\'S REVENUE</h3>',
'<p>{revenue}</p>',
'</div>',
'<div id="orderdata">',
'<div id="orders">',
'<p><span class="label">ORDERS</span>{count}</p>',
'</div>',
'<div id="items">',
'<p><span class="label">ITEMS</span>{items}</p>',
'</div>',
'</div>',
'</div>'
],
}
],
updateWithRecord: function(record){
Ext.each(this.items.items, function(item){
item.update(record.data);
});
},
//*************HACK FIXME***********************
fetchStoreData: function(){
var store = shopifymobile.stores.onlineProductStore;
this.updateWithRecord(store.getAt(0));
store.removeListener('load', this.fetchStoreData);
},
initComponent: function(){
shopifymobile.stores.onlineProductStore.addListener('load', this.fetchStoreData, this);
shopifymobile.stores.onlineProductStore.load();
shopifymobile.views.RevenuePanel.superclass.initComponent.apply(this, arguments);
}
});
EventList.js
shopifymobile.views.EventList = Ext.extend(Ext.Panel, {
layout: 'fit',
items: [
{
id: 'eventList',
xtype: 'list',
store: shopifymobile.stores.onlineEventStore,
itemTpl: [
'<div class="eventitem">',
'<div id="eventdata">',
'<ul>',
'<li>New {verb}</li>',
'<li>{message}</li>',
'<ul>',
'</div>',
'<div id="eventtime">',
'<p>{created_at}</p>',
'</div>',
'</div>'
]
},
],
initComponent: function(){
shopifymobile.views.OrderList.superclass.initComponent.apply(this, arguments);
}
});
When I initialize my Viewport I add a new RevenuePanel and Eventlist to a dashboardIndex object:
shopifymobile.views.dashboardIndex.add(new shopifymobile.views.RevenuePanel());
shopifymobile.views.dashboardIndex.add(new shopifymobile.views.EventList());
The only way I can get the list to somewhat work is if I set it to fullscreen, but since i have a toolbar on the bottom of my screen the last item is being overlapped by it.

The way I've done this is to embed the list inside of a panel, and that panel containing should use layout:fit. I've also had to specify width :100% in the containing panel but that may vary based on your specific case. Here's what I did - note that I'm also using DataVIew and not Panel as the list base, but it should work either way.
var panel = new Ext.Panel({
flex: 1,
frame:true,
autoHeight: true,
collapsible: true,
width: '100%',
layout: 'fit',
items: [
new Ext.DataView({.....} ) ] } );
